2.2 Standard System Configurations
2.2.1 System Configuration for Speed Control
If the BPS-4H needs to be operated as standalone system a handheld user panel (LUI-A.1) can be attached
to the RS232 port of the controller allowing the operator to set the speed manually (see Figure 3).
For external control with analog and digital signals a designated PLC module (PLC-A.1) can be attached to
the controllers PLC interface allowing to set the speed with an analog signal and control operation with various
digital signals (see Figure 3). For more sophisticated operation and control the RS232 port on the controller
can be used. Contact Levitronix
®
for the relevant protocol.
A computer can be connected via the RS232 interface to allow communication with Levitronix
®
Service
Software. Hence parameterization, firmware updates and failure analysis are possible.

2.2.2 System Configuration for Process (Pressure or Flow) Control
Precise flow or pressure control can be realized in a closed loop together with a flowmeter or pressure sensor
as illustrated in Figure 4. Levitronix
provides either turnkey solutions for closed-loop flow control or helps to
design your own flow control system. In addition to the flow control function, the Levitronix
control firmware
comes with several condition monitoring features to monitor the integrity of the fluid circuit. Levitronix
flow
control systems can generate alarms for preventive filter exchange, no-flow conditions or line clogging.
Dynamic Condition Trending (DCT) enables failure prediction and scheduling of preventive maintenance.
